Development and analysis of Keil compiler constructs for an Embedded application for ARM Architecture

Abstract

In recent years the supremacy of embedded system has increased tremendously in such a way that it has impinged into all the mobile and multimedia applications. While designing an embedded system application, apart from execution speed, the most important factor that has to be considered is the total cost of the system. Most of the application that run on embedded platform faces a common problem with the availability of restricted or very small memory area available for storing the application program. The cost of the embedded system mostly depends on the amount of memory used. Reducing the code size is a straight forward solution to minimize the memory used by the application program. This paper is an implementation of a compiler using Keil tool for an ARM7TDMI-S microprocessor for an embedded application which will reduce the code size to approximately 5% of a code which has already passed through all the levels of optimization embedded in the Keil compiler. A compiler is said to be retargetable, if it can be applied to a range of different target processors, by re-using most of the code. This means that target model cannot be an implicit part, but must be specified explicitly.
